Any ideas or illumination?
Chances are, your system uses intel_pstate driver for frequency
scaling rather than acpi_cpufreq, and cpupower still tries to set
"ondemand" governor that is not supported there.
See 'cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver'.
If it is "intel_pstate", then see what is in
/etc/sysconfig/cpupower. Chances are, it contains the following:
CPUPOWER_START_OPTS="frequency-set -g ondemand"
CPUPOWER_STOP_OPTS="frequency-set -g ondemand"
You can change "ondemand" to "powersave" there, then try to start
cpupower.service again.
I fixed a similar problem in ROSA some time ago, not sure if
OpenMandriva has analogous fixes as well.
Note that this "powersave" governor is not the same as the
"traditional" "powersave" governor for acpi_cpufreq, so do not worry
that "ondemand" is not used.
By the way, the list of available governors is available in
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors.

It is maybe not an idea to make it depend to intel tools or something,
because this cpu powersaver it is an spezific tool for intel
periphery then ,
if i have understood right . so, maybe build up an small package
together
with some other inteltools and enable by install the specific
intel-tools ..
and remove it from the standard install package because,
the cpupowersaver it's spezific and let enable the service by install.
best regards
Blacky
